SPECIFICATION forming part of Letters Patent No. 554,353, dated February 11, 1896.

Application filed September 6, 1893.

To all whom t may concern:

Be it known that I, CHARLES F. UEBEL- ACKER, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain 5 new and useful Improvements in Electric Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to ro make and use the same.

My invention relates to an improvement in electric locomotives, and more particularly to means for supporting the motor and protecting the gearing.

IIeretofore it has been proposed to mount at least one end of the motor-frame of an electric locomotive directly on one of the axles of the car. It has been found in practice that with the motor-frame thus mounted directly7 :o on the axle when an obstruction or unevenness of the track is encountered the jar occasioned thereby will be transmitted directly to the motor-franie and the motor carried thereby, frequently resulting in more or less 5 serious damage to the motor and its frame, as

well as to the track.

It is the object of my invention to obviate the objections encountered in such prior devices, and to so mount or suspend the motor o that the irregular movements or vibrations of the axle will be taken up by devices located intermediate of the axle and motor, so that suoli irregularities in the movements of the axle will not affect the motor or its support 5 ing-frame.

XVith this object in view my invention consists in certain features of construction and combinations of parts as will be hereinafter described and pointed out in the claim.-

In the accompanying drawings, Figure lis a plan view of my improvements. Fig. 2 is a side view. Figs. 3 and 4c are detail views. Figs. 5, 6, 7, and 8 illustrate different embodiments of my invention.

5 A represents a truck-frame comprising, in its general structure, parallel bars a, and B represents a car-axle. Disposedabove the parallel bars a a is a cross-bar b, which is connected with the bars a by means of bolts b',

and between the ends of the cross-bar b and the bars a springs c are located.

Serial No. 484,942. (No model.)

Loosely mounted at or near its end on the axle B is a U- shaped swinging or guiding frame C comprising parallel arms CZ CZ and a rear connecting-bar d', said bar d being 55 loosely connneeted with the cross-bar b by means of a bolt or rod c. A spring f is disposed between the erossbars I) and d and eucircles the bolt or rod e.

At the free end of the swinging or yielding 6o frame O bearings g are made for the reception of lugs 7L projecting from the motor, which lugs preferably contain bearings for the armatureshaft t' of the electric motor D. The casing E of the motor is secured to the cross- 65 bar Z) by means of suitable bolts. From this construction and arrangement of parts it will be seen that the motor D is yieldingly suspended, not only at one end from the truckframe, but also directly over the axle, the 7o gears being kept iu mesh by the arms d d, which are preferably east with the cross-bar d', so that when the wheels of the car strike an obstruction or encounter unevenness in the track the jar occasioned thereby will be 7 5 taken up by the interposed springs, and the motor will not be subjected to the disastrous results which such jars would cause were the motor mounted directly on the axle, nor will its weight cause so heavy a blow upon the 8o track as if it were mounted unyieldingly upon the axle, as in the present practice.

In order to transmit motion from the armature of the motor to the axle, the former will be provided with a pinion 7c adapted to mesh 8 5 with a gear Zon the latter. It will be observed that as the motor-shaft is parallel with the axle, and that as the frame C is loosely mounted on the axle, the pinion k and gear Z will always be maintained in mesh.

Heretofore it has been customary, for the protection of the gearing from dirt, dac., to inolose the same in a hood secured to the casing of the motor. It has been found in practice that when the hood is supported in this man- 9 5 ner the jarring received by the motorframe causes the fastenings of the hood to the casing to work loose and release the hood to a greater or less extent. In order to obviate this, I cast a hood or box F, for the reception roo of the gearing, integral with the U-shaped frame C, so that its movements will be coin-- cident with those of said frame, and therefore it will not be liable to become broken or detached therefrom.

It is evident that slight changes might be made in the manner of supporting the motor without departing from the spirit of my invention or limiting its scope, the important feature of the invention being the suspending of the motor in such manner that it is not obliged to rise and fall with the rise and fall of the axle which it drives, and at the same time maintaining the gearing in the proper relative positions.

In Figs. 5 and 6 I have illustrated one modification of the arrangement of yielding suspending devices. In this form of the invention a lug m is made to project from one end of the casing E and perforated for the accommodation of a bolt m', which also passes through one of the bars of the truck-frame. A spring a is disposed between the lug m and bar of the truck-frame and encircles the bolt or rod m', this spring corresponding to one of the springs c of the preferred form of the invention. Laterally-projecting lugs o are made on the rear end of the casing E and are perforated for the accommodation of rods or bolts d, which also pass through the parallel arms of the U-shaped frame C. Springs p are disposed between the lugs o and the arms d of the U-shaped frame and encircle said bolts or rods o.

In the form of the invention shown in Figs. 7 and S the spring n is arranged the same as in the form shown in Figs. 5 and G, but instead of providing two springs p only one of such springs is provided, and that one is disposed on a rod or bolt q, passing through a lug q', projecting rearwardly from the casing E and through the apex of a V-shaped bracket q2, proj ectin g from the arms d of the U -shaped frame C and terminating immediately over the lug q.

In all places where springs are located, in the various forms of the invention, I prefer to place them both above and below the parts on which they act.

Various other chan ges than those above described might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope; but,

IIaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In an electric locomotive, the combination with a truck-frame and axle, of a transverse bar extending over the axle, springs between the ends of said transverse bar and the truckframe, a U -shaped frame mounted at one end on the axle, said frame comprising parallel arms and a connecting-bar, the latter being disposed parallel with and in close proximity to the axle, a spring disposed between said last-mentioned bar and the transverse bar on the truck-frame, and an electric motor mounted in the free end of the U-shaped frame, said motor being secured to the transverse bar on the truck-frame, a gear-wheel on the axle, a pinion on the armature-shaft of the motor, and a casing for said gearing carried by the U-shaped frame, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
